the short answer is that you need something to re-open the searcher -- but i'm not going to go into specifics on how to do that because...
You are dealing with a VERY low level layer of the lucene/solr code stack -- w/o more details on why you've written this particular bit of code (and where in the solr stack this code lives) it's hard to give you general advice on the best way to proceed and i don't wnat to encourage you along a dangerous path when there are likely much easier/better/safer/more-supported ways to do what you are trying to do -- you just need to explain to us what that is. https://people.apache.org/~hossman/#xyproblem XY Problem Your question appears to be an "XY Problem" ... that is: you are dealing with "X", you are assuming "Y" will help you, and you are asking about "Y" without giving more details about the "X" so that we can understand the full issue. Perhaps the best solution doesn't involve "Y" at all?
